A light-emitting apparatus includes a light source unit for emitting a first excitation light beam, a beam shape conversion unit for reflecting the first excitation light beam and outputting the reflected first excitation light beam as a second excitation light beam, and a driving unit for driving the light source unit, wherein the beam shape conversion unit includes a plurality of reflective surfaces having different reflection patterns, and the reflective surfaces are arranged in a direction that intersects the direction in which the first excitation light beam is incident.
